One of those potential swing votes has already come out against the Colorado judge. Pennsylvania’s mild-mannered senator, Bob Casey (D-PA), also announced on a press call Thursday morning that he will oppose Gorsuch, both in an up-and-down vote and, as Schumer instructed, on a cloture vote.

“I don’t believe that Judge Gorsuch, his judicial approach, would ensure fairness for workers and families in Pennsylvania and indeed across the country and I will not support his nomination,” Casey said.

It’s an bold move for Casey, whose home state Trump won in 2016. Casey’s Pennsylvania colleague, Sen. Pat Toomey (R-PA), said he would vote to confirm Gorsuch.

Interestingly, in 2009 when he was campaigning for the Senate seat he now holds, Toomey said he would have voted in favor of President Obama’s nominee, Sonia Sotomayor.
